## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402-data-api-seller-profile-lookup-7727e727
```

Example prompt: Pull up the full x402 seller profile for https://api.example — show me all their listed APIs with prices and payers, their total call volume over the last 30 days, their mean uptime, and their payTo address.

## When to prefer this

Use this endpoint when you need the complete profile of a single known x402 seller by its origin URL — including its full API catalog, per-API pricing and payer counts, aggregate call volume, uptime, and payTo addresses. Prefer this over the rankings or trending endpoints when you have a specific origin in mind and want exhaustive per-seller detail rather than cross-market comparisons.

## Known failure modes

- Origin not found in registry — returns empty results or 404-equivalent if the origin has never been listed
- Malformed origin URL (missing https:// scheme or exceeds 300 chars) — request rejected with validation error
- Seller has no active listings — returns valid response with empty results array and zero counts
- Payment failure ($0.003 USDC not fulfilled) — request blocked with 402 Payment Required
- Upstream data freshness lag — uptime and payer counts reflect rolling 30-day window and may be up to 6 hours stale

## How this service works

Everything one x402 seller (origin) lists: its APIs with prices, payers and uptime, its total calls, its payTo addresses, and since when it is listed.

## Output

A JSON object containing the seller's origin URL, total number of listed APIs, an array of individual API resources each with its price in USD and 30-day payer count, aggregate 30-day call volume, mean uptime over 30 days, and payTo address(es) with listing date.
